Description:
We report Muon Spin Resonance spectra for Si 0.06 Ge 0.94 that can be attributed to undissociated shallow muonium acceptors. This effective mass acceptor state is a paramagnetic center with the core consisting of either the negative charge state of muonium trapped in a tetrahedral interstitial void or a negatively charged Si-Mu complex. Two shallow acceptors are observed with differing hyperfine interactions and symmetries suggesting two preferential sites with different local chemical environments, implying that both states are present.
